Abstract

P300 and contingent negative variation (CNV) were recorded in depressive inpatients with and without history of suicide attempt. The results showed a significant reduction of P200, P300, and CNV and a significant increase of postimperative negative variation (PINV) in patients who had attempted suicide compared to patients with a negative history. Moreover, P300 amplitude was negatively related with the Suicidal Risk and the Hopelessness but not with the Hamilton scales. These results stress the need to differentiate clinical subgroups of patients to assess the psychophysiology of depression, and indicate that patients who attempted suicide exhibit lower cortical resources and poorer cortical performance than patients without history of suicide attempt.
